To all fwhom t may concern.'

Be it known that I, EMIL HUGO FISCHER, a citizen of the United States,residing at the city of Milwaukee, countyof Milwaukee, and State ofWisconsin, have invented certain new and useful Improvements invTemporary orL'oose-Le'af Binders, of which the following is aspecification. This invention relates'to improvements in temporary orloose leaf binders.

.The object of the invention is to provide a loose leaf binder of thepin and follower type which is simpleV in structure, economical tomanufacture, andconvenient and` elii- Icient in operation. j

Further objects, and objects relating to `structural details, willdefinitely appear rfrom the detailed description to follow.

I accomplish the objects of my invention 201 by the devices and'meansdescribed in the following specification. The invention is clearly`dened and pointed out in the claims.

A structure which is apreferred embodiment of my invention is clearlyillustrated in the accompanyingA drawing `forming a part ofthisspecification, in .which Figure I is a plan view of my improved binder,portions ofthe covers being broken away.V

`-Fig. vII is an enlarged sectional ydetail Y taken on a linecorresponding to line 2 2 rrofFigI.

"FigLIIl is` an inverted view ofthe follower, withy the baser barremoved. Fig. IV is a plan View of the base bar, showing the clutchmembers and spring de- 'tent mounted thereon. n A In the drawing,similar reference characters refer to similar lparts throughout theseveral views, andthe sectional view is taken looking in the directionof the little arrows at the ends of the section line.

Referring to theg drawing,

pair of binder members,

ally by the numerals 1 and 2. For convenience, these binder memberskwill be designated as upper and lower binder members.

vThe binder members illustrated are provided with covers connectedthereto by iexible 'hinge members 3 in the k"well-known manner.Bindingposts 4 are secured to the lower member. Y y' y The upperbinding'member,comprises a base bar 5 and a channel-shaped housing 6inverted thereon and secured by means of I` provide a k10 which, informed of a designated genertongues 7 extending through holes 8 in theends of the base bar.

I provide a pair of clutch members 9 and the structure illustrated, areflat blade spring 11. This spring is secured to the plate 5 on the basebar 5 by means of rivets 12. The clutch member 10 is provided with apair of upwardly and inwardly inclined tongues 13. The base bar hasslots 14 extending from'65 one edge to receive the posts, while thespring clutch members project slightly Vover these slots to engage theposts.

The housing is provided with slots 15 registering with the slots 14;. Alocking bar or 70 lslide 16 is mounted in the housing and provided atone end with outwardly and downwardly inclined cam lingers 17 whichengage with the tongues 13 of the clutch member 10 to disengage thisclutch member. y7.5 The opposite end of the locking bar is bent uponitself as indicated at 18 and its end is bent inwardly and downwardly toprovide an inclined cam member which projects be 4 neath the end of theclutch member 9. 80

The locking Vbar 16is provided with L- shaped slots 19 and 20 adapted tobe brought into register with the slots of the binder member.

' The extensions 21 and 23, and 22 and 24; 85 formed bythese L-shapedslots extend across 'and close lthe binder member slots when the lockingbar is moved to permit the clutch members to engage and move out of thev. binderk member slots when the locking bar yis shifted to release theclutch members.

A spring detent 25 is secured to one end of the base bar 5 and isprovided with a 'leeper 26 engaging the locking bar to hold 1t inadjusted position. A button 27 lis se- 95 cured to the locking bar bymeans of the shank 28 which projects through the slot in the housing.

In Fig. II the locking bar is shown in., position to permit the clutchmembers to env gage. When it is desired to release the binding posts thebutton 27 is moved to- `ward the right whereupon the cam portions of theslide engage beneath the tongue 13.. and on the end of the clutch member9 lift` 105 ing the clutch members out of clutching relation and openingthe slots in the upper binder member so that it Inav be moved laterallyfrom the posts. Having thus described my nventlon, what with said slideto hold it in its adjusted positions.

7. In a binder, the combination of a binder member provided with posts,a clamping member provided with post openings, a clutch spring securedintermediate its ends to said clamping member between said post openingsthereof, the ends of the spring c011- stituting clutch members adaptedto engage the posts, said spring being provided adjacent one end with anupwardly projecting tongue, and a clutch control slide provided withdownwardly inclined cams coacting with one end of said clutch spring andwith said tongue on said clutch spring so that 15 both clutch membersare actuated by the shifting of said slide.

In witness whereof I have hereunto set my hand and seal in the presenceof two witnesses.
